Highly electronegative metallic contacts to semiconductors using polymeric sulfur nitride [PDF]

, 1976
The Schottky barriers formed on n‐ZnS and n‐ZnSe by polymeric sulfur nitride have been compared to barriers formed by Au. Barrier energies as determined by photoresponse, current‐voltage, and capacitance‐voltage methods show that (SN)_x is approximately ...

Real‐Time Kinetic Monitoring of Dental Composite Photopolymerization by Photo‐DSC

Journal of Applied Polymer Science, EarlyView.
Real time photo‐DSC was used to investigate polymerization kinetics of Bis‐GMA/TEGDMA dental composites. The study thoroughly examines how photo‐initiator type, concentration, silica filler content, and moisture affect conversion and curing rate. Results highlight optimal initiator systems, filler effects, and moisture tolerance, providing valuable ...

Learning to explain environmental crises: A dialogic analysis of teacher professional learning between Chile and the United States

British Educational Research Journal, EarlyView.
Abstract Many studies and initiatives are animated by the potential for science education to intervene in the climate crisis and crises of environmental degradation and disinformation. For science teachers to learn to address these issues in their classes, their teaching must expand beyond scientific facts and face controversial social aspects. Dealing

An efficient new route to dihydropyranobenzimidazole inhibitors of HCV replication. [PDF]

, 2010
A class of dihydropyranobenzimidazole inhibitors was recently discovered that acts against the hepatitis C virus (HCV) in a new way, binding to the IRES-IIa subdomain of the highly conserved 5' untranslated region of the viral RNA and thus preventing the

Mononuclear Molybdenum and Tungsten Phosphine Complexes for Catalytic Ammonia Synthesis: Development of the pentaPod Concept

ChemPhysChem, EarlyView.
The pentaPod (P5) concept unites tridentate and tripodal fragments to form molybdenum and tungsten catalytic Chatt‐type complexes for N2‐to‐NH3 reduction. Two pentaPod ligands, P5Me and P5Pln, are available with either two dimethylphosphine or phospholano (Pln) groups. The complexes enable the investigation of reactivity differences in N2 reduction and,

A Mucoadhesive Hydrogel for Precise Resveratrol Delivery in the Management of Inflammatory Bowel Disease

Food Frontiers, EarlyView.
CMTR‐Gel targeting to the inflamed mucosa by electrostatic interactions. ABSTRACT Natural drug‐food homology compounds have vast therapeutic potential, particularly for inflammatory bowel disease (IBD), but their poor water solubility, instability, and limited mucosal availability hinder their clinical translation.
